- Made of natural stone
- Dry heating: the element is separated from the water by a steal sleeve
- Easier maintenance: the replacement of the element does not require emptying the tank
- Galvanic protection of the element, as it does not come into direct contact with water
- Scaling protection: the protective sheath is blue silicone enameled. Furthermore thermal charge is distributed in a larger section (namely the steath) then in wet operating elements, thus decreasing limestone aggregation
- Longer life of the product, since the stress on part and components is reduced.
The appliances, entirely manufactured in Italy, are made with high quality steel.
Moreover, for each different component, the specific alloy or type of steel is used, in compliance with the necessary characteristics to convey to the component itself. At the moment of the edition of the present catalogue, 27 different metal sheets are used in the factory.
The inner surface of the tank is protected by a powder enameling treatment “Blue Silicon”. It is carried out using the most modern technologies for electrostatic application and then it is vitrified at 850°C. Perfection of the result is double checked on every single water heater manufactured, through laser thickness gauge and photo-optic meter.
All models are equipped with a high concentration anode, in order to grant the maximum protection against electro-chemical reactions and safeguard the tank from corrosion.
Consumptions reduction along with environment respect is crucial to Ferroli water heaters design and manufacture. As to insulation infect a high performance water blown polyurethane has been chosen and used, combining top performances and absolute lack of CFC or any other dangerous substance release. Furthermore, the appliances have been conceived to be highly recyclable after their disposal.
Every water heater is tested during the different production phases, to ensure the maximum quality, efficiency and operational longevity. Laboratory tests are performed periodically to verify the compliance to the declared performance data.
Security of the appliance is surveyed by thermostat with double safety system and a pressure relief valve, with must be integrated in the system installation with the additional safety devices eventually required by the local law or European directive EN 1487, where applicable.
Ferroli water heaters do not require particular maintenance precautions and will operate for long time.
They have been designed to permit easy replacement of materials subject to wear, in particular should water be aggressive of chalky.
Flanged electric group are mounted on large 120mm flange with 70mm manhole, sealed by thick EPDM flexible gasket. It enables comfortable access from inspection and periodical anode replacement
